What is the actual state of President Trump's health — now and over the past 24 hours?

Why it matters: It’s one of the most high-stakes questions in the world, and Jonathan Swan writes that he cannot answer it, despite having spent since 5 a.m. on Friday on his phone with sources inside and close to the White House.

On Friday night, we chose not to publish information we'd learned from well-placed sources who told us the president had experienced a fever and was worse than the White House was letting on.

• We chose not to publish because we weren’t certain enough it was correct, and it was no time to lower our editorial standards.

Today, when we saw the doctors line up outside Walter Reed in their white lab coats, we thought we might finally get clarity.

• The picture painted by the White House physician, Navy Commander Dr. Sean Conley, was rosy: Trump was in good spirits — so good, apparently, he had been fever-free for 24 hours, and felt he could have walked out of Walter Reed today.
• The Q&A didn't engender confidence. Trump's doctor was repeatedly evasive on the question of whether he’d received supplemental oxygen. But the picture remained rosy.

Then, minutes after the doctors' press conference, something extraordinary happened that crystallized this White House’s credibility gap, and made a mockery of any reporter trying to responsibly cover this president’s condition.

• The White House reporter on pool duty — traveling with the president and delivering official dispatches to reporters at numerous outlets — sent this dispatch, quoting "a source familiar with the president’s health":

The president’s vitals over the last 24 hours were very concerning and the next 48 hours will be critical in terms of his care. We’re still not on a clear path to a full recovery.

That was a much more worrisome portrait. The source, identified by AP, was White House chief of staff Mark Meadows, who was shown on camera asking the pool to "go off the record with some of y'all."

• I have tried to get a straight answer from the White House since then about what is going on, and why we are being fed official contradictions.

The bottom line: Multiple sources in the White House and on the campaign have reached out since Meadows' statement, and said they're utterly perplexed about what's going on.

• They, like us, have little confidence in what they are being told.

About two hours after the briefing, Dr. Conley issued this "clarification" about when President Trump was first diagnosed.

Why it matters: Conley's initial statement would have meant that Trump kept his diagnosis secret for 36 hours.

Trump supporters gathered outside Walter Reed and others blew their horns as they drove past, providing an accompaniment for cable news reports.

Tomorrow's Patriots-Chiefs game has been postponed after "positive COVID-19 tests on both teams," the league said in a statement today.

• ESPN's Adam Schefter reported that Patriots quarterback Cam Newton tested positive.
• The game will be rescheduled to Monday or Tuesday.

P.S. from the college football ranks: TCU upset the #9 Texas Longhorns 33-31.
